Description
The present invention relates to the special purpose vehicle that a kind of dosing is used, it is to utilize near its water source, directly prepares the large flow liquid distributing pump vehicle of mixed liquor.
As the most oil fields of present China is to be mixed with glue at make-up station, transports to the well site with tank car then, is pumped in several receivers, uses during in order to pressing crack construction.
Powder content only is 0.5～1% in the glue owing to become, and annex solution also only is about 0.5%, and therefore a jar vehicle borne overwhelming majority is a clear water, and the well site at water source is arranged near particularly away from make-up station, more than its vehicle, the height of expense, causes construction cost to increase.
In order to reduce the pressing crack construction cost, if can utilize near water source, well site, directly be mixed with glue, then be the best way.China has two kinds of equipment can realize this method at present.
The one, some Oilfield using liquid distributing vehicle group of China is to the direct dosing in well site.This car group is made up of three car: one is that self-control liquid distributing vehicle, one are the self-control pump trucks, also have one to be to load the powder that dosing uses and the carrier of annex solution.Join several tank cars simultaneously fully.
The tank car function is near the water source La Shui well site.It will draw the clear water that comes to pour in the tank on the well site, till filling after, it is stand-by to pull on water.
The liquid distributing vehicle function is that tank of preparation becomes glue.It is by the diesel engine drives reciprocating pump on the ride, by the reciprocating pump suction ﹠ delivery water hose, clear water in the tank is pumped into funneling mixer, the operative employee pours one bag of bag powder in the funnel into and mixes with clear water, and annex solution is directly poured in the tank by the operative employee, and mixed liquor turns back to tank by mixer discharge opeing sebific duct, sucks and be pumped into mixer by the reciprocating pump water suction hose from tank again, the dosing that circulates so repeatedly is till a tank clear water is formulated as into glue.
The pump truck function is that the one-tenth glue in the tank is pumped in several receivers of well site.Diesel engine drives centrifugal pump on the ride, by centrifugal pump suction sol pipe, the one-tenth glue in the tank, through the well site manifold be connected sebific duct, be pumped in several receivers till.
Then tank car discharges water into groove, and the liquid distributing vehicle dosing becomes glue, and pump truck is pumped into jar, said process so repeatedly, and till the one-tenth glue total amount of preparation reached the construction requirement consumption, liquid distributing vehicle group and several tank cars all returned then.
The 2nd, patented product " liquid distributing pump vehicle that is used for the oilfield " (number of patent application: 89219711.0) direct dosing of employing applicant what in November, 1989 application to the well site.For distinguishing " large flow liquid distributing pump vehicle " patent of this application, this manuscript claims that the former is " 89 liquid distributing pump vehicle ".
89 liquid distributing pump vehicles are autotrucies, are equipped with on its chassis:
1. driving system.It is that automobile engine power is passed to two centrifugal pumps and a dry powder feeding roller.Drive path is:
Automotive engine-power takeoff-universal drive shaft-auxiliary gear box-two centrifugal pump, another output shaft-double-united oil pump of power takeoff-hydraulic tubing-governor valve, change-over valve-two HM Hydraulic Motor-two a dry powder feeding roller, the HM Hydraulic Motor rotating speed is regulated by governor valve, realizing dry powder feeding roller powder feeding flow regulating, every dry powder feeding roller is worked respectively to switch by change-over valve and is realized.
2. liquid mixing system.It is the working portion that is mixed with glue, and it comprises:
The self-sucking device that centrifugal pump of using for clear water, starting pump priming are used, jet mixer (have on it three inlets: clear water, powder, annex solution, a mixed liquor discharge orifice), and suction water (liquid, powder) pipeline and various valve.
3. pumparound.It is that mixture pump is delivered in the receiver of well site, and it comprises:
A fluid storage tank, the centrifugal pump that the pumping mixed liquor is used, and suction liquid pipeline and various valve.
4. powder feed system.It is that it comprises with powder supply jet mixer:
Two powder jars, two dry powder feeding rollers, two cover powder jar taperings link to each other with the compressed air units in cars system blows the loose powder materials device.Only use a powder jar and a dry powder feeding roller during dosing, all the other are stand-by, wait a powder jar powder to use up after, switch to another powder jar and another dry powder feeding roller by hydraulic directional control valve.
5. monitoring and metering meter system.It is to monitor each relative section working parameter of metering in dosing work, and it comprises:
Clear water turbine flowmeter and its electromagnetic signal sensor, dry powder feeding roller and its electromagnetic signal sensor, four parameters such as dosing gauge-combine can numeric display centrifugal pump clear water instant flow rate, clear water cumulant, powder weight, powder water compare, the delivery gauge of centrifugal pump speed gage and automobile engine oil temperature table, oil pressure indicator and two centrifugal pumps.
6. maneuver control device.
The dosing of 89 liquid distributing pump vehicles and pumping flow process are worked in the following order:
The dosing flow process: it is to be bled by the self-sucking device on the suction line between well site tank and this centrifugal pump to realize that a centrifugal pump prestart is poured water.Centrifugal pump starting back clear water enters the delivery piping between pump and the jet mixer, is pumped in the jet mixer through turbine flowmeter, because the clear water jet action is entered powder mouth place at mixer and produced vacuum.Powder in the powder jar falls into powder inlet pipe inflow point via the dry powder feeding roller of fluid motor-driven, powder flows into mixer through powder inlet pipe under vacuum action mixes with clear water, annex solution also flows into mixer under jet action mixes with clear water, the fluid storage tank of mixed liquor on mixer drain pipe inflow ride.
The pumping flow process: another centrifugal pump sucks the mixed liquor in the fluid storage tank by the imbibition pipeline between fluid storage tank and the pump, and centrifugal pump enters the manifold on the well site by drain pipe, delivers in several receivers of well site by connecting rubber pipe pump.
After the powder dosing in first powder jar uses up, exchange above-mentioned two centrifugal pump functions, be that the centrifugal pump that the dosing flow process is used becomes pumping usefulness, the centrifugal pump that the pumping flow process is used becomes dosing and uses, close simultaneously and open respective valves and conversion water suction hose, switch change-over valve then, make second the dry powder feeding roller work below the powder jar, mix with clear water for powder to another jet mixer, the dosing of back and pumping flow process are ditto described.
Above diagram of circuit can see 89 liquid distributing pump vehicles for details, and (number of patent application: 89219711.0) the patent application specification accompanying drawing 3.
The liquid distributing vehicle group is compared with make-up station, and for away near the well site that the water source is arranged the make-up station, it can reduce the pressing crack construction cost greatly, but also there are many shortcomings in it.
1. dosing speed is slow, and receiver is gone in dosing continuously.
Because liquid distributing vehicle is to use the reciprocating pump dosing, its dosing speed is 0.5m
3/ min is so dosing speed is slow.Because dosing is a tank circulation dosing, and pumps into receiver by pump truck, so receiver is gone in dosing continuously in batches.
2. dosing quality is low, and powder consumes high.
Because liquid distributing vehicle adopts open type manually intermittently to add powder, thereby mix inhomogeneously, water bag powder phenomenon often occurs, so the dosing quality is low, the weather effect of being blown is simultaneously often blown away the part powder, the powder that in addition manually falls is easily overflowed and is scattered in the well site, so powder consumes height.
3. many expenses of the many people of car height.
The liquid distributing vehicle group is made up of respectively three car and is realized the transportation raw material, joins aqueous liquid, is pumped into jar three kinds of difference in functionalitys, but needs driver 3 people, pump worker 2 people, operative employee 2 people altogether, amounts to 7 people.
4. labour intensity height, environment easily pollutes.
Liquid distributing vehicle adopts open type manually to add powder liquid feeding mode, and labour intensity height, dust easily suck in the human body lung, and powder easily is scattered in the well site, the weather of blowing especially, the easier pollution of environment.
5. metering is by manually inaccurate.
89 liquid distributing pump vehicles are compared with the liquid distributing vehicle group, and it can overcome latter's shortcoming, but still have many weak points through using:
1. because of flow setting is that two pumps is respectively applied for dosing and two flow processs of pumping, because mixed liquor contains gas, so dosing speed is difficult to reach designing requirement.
Two centrifugal pumps are arranged on the ride, and pump and mixer are used for the dosing flow process, and another pump is used for the pumping flow process.Because powder delivers into mixer by the negative pressure strength, institute is the mixed liquor that contains gas through the liquid that mixer enters fluid storage tank, and it is pumped the centrifugal pump suction that flow process is used.Because of centrifugal pump sucks the mixed liquor that contains gas, its flow must descend, though the centrifugal pump that dosing is used can reach 1.5m
3/ min, but the centrifugal pump that pumping is used can only arrive 1m
3/ min.Excessive for fear of the fluid storage tank mixed liquor, the centrifugal pump flow that dosing is used has to be transferred to 1m
3/ min is so dosing speed is from being difficult to reach requirement.
2. the jet mixer annular is dusted, and mouth is easy to be stopped up, and is difficult to remove.
Jet mixer center nozzle is to have to press the clear water injection orifice, with the concentric annulus area of center nozzle be the powder mouth that dusts.Because clear water drops in water smoke on the mouth that dusts when spraying unavoidably, powder is made moist slowly be bonded in the mouth that dusts, result's mouth that dusts that results in blockage that is in operation, simultaneously because of structural relation, being in operation is difficult to tamper mouthful is disposed from dusting.
3. because of compression tolerance is too little, powder is difficult to flow in the dry powder feeding roller in the powder jar.
Because of the big viscosity height of powder internal friction of mixing usefulness, be difficult for dirty jar of end from the jar tapering, compressed air units in cars tolerance is too little simultaneously, and the crosswind that gives jar tapering is difficult to blow powder to be made it to suspend, so a powder is difficult to flow in the dry powder feeding roller in the jar.
4. a powder tankage size is little, and its powder does not satisfy finishes the requirement of a bite well dosing amount.
Two powder jars are arranged on the ride, and when the powder in the powder jar does not satisfy when finishing a bite well dosing amount demand, 89 liquid distributing pump vehicles need termination of pumping, exchange the dosing and the pumping flow process of two centrifugal pumps, switch change-over valve then, use the dry powder feeding roller below another powder jar, make its powder participation dosing down
5. do not contain the liquid case of annex solution on the ride, need one fortune to add the carrier of liquid feeding.
89 liquid distributing pump vehicles have the transportation powder, and water distribution becomes glue, are pumped into functions such as basin, but do not transport the annex solution function, so during to the well site dosing, also need the carrier of one roping annex solution.
6. hydrostatic drive drives the dry powder feeding roller, its complex structure, and element is many, and Hydraulic Adjustable Speed changes dry powder feeding roller rotating speed, and its fault is many.
7. digital display dosing gauge has only four parameters, does not have annex solution cumulant and liquid water than two parameters, measures incompletely, uses inconvenience.
The purpose of this invention is to provide a kind of large flow liquid distributing pump vehicle that overcomes above-mentioned two kinds of prior art deficiencies, to satisfy the dosing needs.
The summary of the invention of large flow liquid distributing pump vehicle and technical characterictic describe in detail in conjunction with the accompanying drawings and embodiments.

2. when designing this mixer 11.1, it not only has the function that clear water mixes with powder, and has a mixed liquor function that pumping contains gas, the gas mixed liquor that has that is mixer outlet still has certain pressure, it can overcome drain pipe 23,25 and be connected the sebific duct hydraulic loss with receiver with manifold 26 and manifold, also has receiver height lift;
3. an annex solution inlet is arranged below the discharge-service valve 9 of mixer 11.1, so that mix to becoming glue with mixed liquor, this annex solution pumps into the annex solution in the liquid case 5 by adding liquid pump 33;
4. mixer drain pipe 23 is not held non-return butterfly valve 41 is housed.When water service pump 21 is shut down; SELF CL immediately under the high-order fluid pressure of non-return butterfly valve in receiver; prevent to become in the receiver glue to pour in down a chimney mixer; particularly do not close mixer powder entering valve 12 before the termination of pumping; this moment as no non-return butterfly valve; one-tenth glue in jar will pour in down a chimney into the back jar, cause serious accident.
This car water service pump 21 is big flow centrifugal pumps, and its flow is 3m
3/ min, and 89 liquid distributing pump vehicle water supply centrifugal pump flows are 1.5m
3/ min, the centrifugal pump because of discharge opeing in its pumping flow process sucks the one-tenth glue that contains gas, and its draining flow can only be 1m
3/ min, excessive at fluid storage tank in order not make into glue, water supply centrifugal pump flow has to transfer 1m
3/ min, i.e. dosing speed is 1m
3/ min, and large flow liquid distributing pump vehicle does not have this problem, so this car dosing speed is 3 times of 89 liquid distributing pump vehicles, is 6 times of liquid distributing vehicle group.

Fig. 4 is the mixing pumping plug-removing device scheme drawing of large flow liquid distributing pump vehicle.
Mouth is easy to be stopped up for the jet mixer annular that solves 89 liquid distributing pump vehicles is dusted, and be difficult to the defective in dosing work, removed, these driving skills art scheme implementation example is the mixing pumping plug-removing device among Fig. 4, it comprises two parts: the one, mixer 11.1, its by water inlet bend pipe 11.1.1, advance powder compound tube 11.1.2, dust and chew 11.1.3, mix pumping line 11.1.4 and form; The 2nd, broken down device 11.2, it is made up of drift 11.2.1 and cylinder 11.2.2.This device is vertical installation.
This apparatus function is: mixer has and mixes and pump function, and broken down device has to dust and chews when blocked, at work the function that can remove rapidly immediately.It is compared with 89 liquid distributing pump vehicle jet mixers, and its technical characterictic is:
1. dusting of mixer 11.1 chewed 11.1.3 and is in central authorities, be loaded under the straight length of powder compound tube 11.1.2 into, with the spout of chewing mouthful concentric annulus area that dusts that dusts be that the water injector of pressing clear water is arranged, and the jet mixer of 89 liquid distributing pump vehicles dust mouthful and the water injector position with above-mentioned just in time opposite;
2. the cylinder 11.2.2 of broken down device 11.2 is positioned at device topmost, and it is located on the bend loss of powder compound tube into, and drift 11.2.1 is equipped with in the cylinder piston rod lower end, and it is on the same axis with dusting to chew.
Just because above-mentioned technical characterictic, just can be by the de-plugging valve 112(change-over valve on the operating console), make the drift of cylinder piston rod lower end move down into to dust and chew mouthful place of dusting, in time removing tamper rapidly.After the commutation of de-plugging valve, move on to original position on the drift, thereby make the mouth that dusts unblocked, continue to dust and mix with clear water.
Whether dust mouthful unimpeded or stop up, the powder mobility status that can observe in current indicator 14 transparent tube decides.
This car is owing to know about stifled device, and the de-plugging valve and the current indicator of serving it, so improved the reliability that mixes dosing.
Fig. 5 is the automobile-used self-sucking device scheme drawing of large flow liquid distributing pump vehicle.
Automobile-used self-sucking device 18 and 45, its structure is the same with size, is respectively applied for water service pump 21 and adds liquid pump 33 prestart pump primings.
It is a T shape three-port structure, is made up of threeway 18.2, nozzle 18.3, joint 18.4 and freeing pipe 18.1.The threeway right side connects nozzle, and nozzle links to each other with joint, and the threeway left side connects freeing pipe.Connection extraction valve 19(or 38 below the threeway) joint hangnail pipe is by flexible pipe and air inlet valve 17(or 40) be connected, freeing pipe communicates with atmosphere.Steel pipe between extraction valve and pump discharge and the discharge-service valve, and continuous near the discharge-service valve place, air inlet valve links to each other with the gas transmission pipe 69e place of blowdown fan by flexible pipe.
In order to accelerate the speed of evacuation, improve self-priming degree of vacuum, the nozzle of this automobile-used self-sucking device and the self-sucking device nozzle of 89 liquid distributing pump vehicles have essential distinction, and this nozzle is a Taper Pipe that shrinks earlier and a bit of pipe and back flaring Taper Pipe fabricate block.When designing this nozzle, make the pipe place gas speed of nozzle reach velocity of sound, flaring Taper Pipe exit gas speed reaches hyprsonic.The self-sucking device of 89 liquid distributing pump vehicles sees " liquid truck that is used for oilfield " (number of patent application: self-sucking device 88221294) for details.
Fig. 6 is the air feed powder feed system scheme drawing of large flow liquid distributing pump vehicle.
Though 89 liquid distributing pump vehicles also have pressurized air to provide crosswind to powder jar tapering, pressurized air source is the gas bag of vehicle compressor, because of its tolerance is too little, is difficult to make powder to flow to the dry powder feeding roller under loosening, thereby influences the dosing normal operation.
This car has two self-sucking devices, and a self-sucking device 18 is to be used for water service pump 21 startings to pour water, and another self-sucking device 45 is to be used to add liquid pump 33 startings to irritate liquid, and the both needs pressurized air as self-sucking device work source of the gas.
This car has two powder jars, and one is back jar 55, divides into rotary feeder 57, it is the work jar, is used for to mixing pumping plug-removing device 11 feed, and another is preceding jar 73, bottom sides is provided with the commentaries on classics powder steel pipe 76 of jar powder feeding backward, and it is a slack tank, and being used for backward, jar changes powder.Every jar powder can satisfy preparation a bite well required powder, and after the back jar required powder of preparation a bite well used up, preceding jar powder was when jar passes on backward, also needs forward jar to provide pressurized air.During jar outside emptying of residue powder of back, also needing backward, jar provides pressurized air in addition.
After the powder in two jars uses up,, powder is sent into preceding jar and back jar by strength conveying powder storehouse or pneumatic cementing truck.
In order to solve the required big discharge capacity pressurized air of above-mentioned first three part, realize down powder flow path, change powder flow path and last powder flow path, these driving skills art scheme implementation example is the air feed powder feed system of Fig. 6, it is made up of the equipment of tape label in the following flow process and parts and container.
Large flow liquid distributing pump vehicle has the powder feeding flow process, and details are as follows for its control step and route:
After this car reaches the well site, at first open back jar steam supply valve 80, back jar blow off valve 62, start blowdown fan 70 runnings then.
Pressurized air enters back jar by following route, is used for looseningly because of automobile the powder by the pier reality of jolting that travels on the way, and waste gas enters well site pick trough, anti-air-pollution in jar.
The fast rotary joint 58-of jar blow off valve 62-total exhaust steel pipe 61-exhaust hose 60-well site pick trough 20 behind powder-back jar exhaust steel pipe 56-in jars 55 behind jar shunting tube 53-sebific duct 51-ball-and-seat 50-nozzle 49-behind jar steam supply valve 80-behind air-fil 71-blowdown fan 70-gas transmission pipe 69-.
Behind the loosening back jar powder number minute, open pressure-relief valve 67, make blowdown fan be in the no-load running state, open air inlet valve 81 then, make rotary feeder 57 bottom f be in atmospheric pressure state.
In the dosing process, back jar powder flows in the rotary feeder by deadweight, is in barometric pressure by mixer at vacuum and the rotary feeder bottom f that chews generation that dust, and its pressure reduction will be fallen the powder for powder steel pipe 82, enter mixer by advancing arogel pipe 16.
In the dosing process, as it is thin to find that powder flows in the transparent tube of current indicator 14, the de-plugging valve 112 of manipulation platform at first, getting rid of dusts chews the blocked fault of 11.1.3, flow still thin as powder, then an explanation back jar powder forms funnel-form greatly because of internal friction, that does not close pressure-relief valve 67, and pressurized air just by above-mentioned route, is blown the powder on the tapering, make that forming funnelform powder stays, and the inflow rotary feeder, it is normal to flow in the transparent tube of current indicator as powder, then loosening after one minute, open pressure-relief valve 67, make blowdown fan be in the no-load running state.
By the time close pressure-relief valve when opening method overcome 89 liquid distributing pump vehicle weak points, flow into the rotary feeder requirement to satisfy back jar powder.
Large flow liquid distributing pump vehicle also has the commentaries on classics powder flow path that 89 liquid distributing pump vehicles do not have: preceding jar powder is transferred to back jar, or back jar residue powder is discharged to the storage powder jar in powder storehouse outward, and details are as follows for its flow operations step and route:
At first to preceding jar or back jar inflation, make tank pressure reach setting value after, change powder flow path again.
Preceding jar of inflation route is as follows: jar 73 before preceding jar of shunting tube of jar steam supply valve 66-77-sebific duct 51-ball-and-seat 50-nozzle 49-before air-fil 71-blowdown fan 70-gas transmission pipe 69-;
Back jar inflation route is as follows: behind air-fil 71-blowdown fan 70-gas transmission pipe 69-behind jar steam supply valve 80-behind jar shunting tube 53-sebific duct 51-ball-and-seat 50-nozzle 49-jars 55.
